摘要：

The anodic oxidation of ultraviolet absorbers in wastewater was investigated on Ti/PbO2 electrodes. Specifically, the effect of current density and pH was examined. After the 180 min of electrolysis at the current density 10 mA center dot cm(-2) and pH 4, the COD removal efficiency and decolorization rate were 98.49% and 99.2%, respectively. Comparing electro-oxidation process with Fenton process, the former removal efficiencies of COD and color were 1.4 times and 1.2 times than that in the latter one. Additionally, the electro-oxidation did not need any chemicals while Fenton process consumed certain amount of chemicals and produced huge sludge. Such studies provided some relevant information about the applicability of electro-oxidation system for treatment of wastewater contaminated by industrial organic synthesis.
